What Are Metal Deck Profiles?
Metal deck profiles are corrugated steel sheets used as structural components in building construction. They serve as permanent formwork for concrete slabs and as roofing substrates. At Cutting Edge Decking, we specialize in three primary profiles: Roof Deck, Composite Deck, and Non-Composite Deck — each available in gauges from 16 to 22 GA with Grade 50 as standard.
Roof Deck (1.5" B)
The 1.5 B roof metal deck features a ribbed profile with a depth of 1.5 inches, providing an excellent balance of strength and lightweight performance. Available in G60 and G90 galvanized finishes, it is ideal for flat and low-slope roofs in warehouses, retail centers, schools, and commercial buildings. The ribbed profile supports insulation systems and is compatible with virtually all membrane roofing types.
Composite Deck (1.5", 2", 3")
Composite deck acts as a permanent form for concrete. After the concrete cures, the embossed deck and concrete work together as a composite unit to resist gravity loads — often eliminating the need for shoring during construction. Available in 1.5", 2", and 3" profiles, composite deck is the primary choice for multi-story office buildings, hospitals, parking structures, and high-rise residential.
Non-Composite Deck (1.5", 2", 3")
Non-composite deck serves as a permanent steel form for the concrete slab but does not develop composite action with the hardened concrete. An excellent choice when the structural design does not require composite behavior — widely used in parking garages, industrial floor slabs, mezzanine systems, and building renovations.
Choosing the Right Profile
Profile selection depends on span requirements, load conditions, fire ratings, and the structural engineer's design. Contact Cutting Edge Decking with your project details — we'll help you specify the right profile, gauge, and finish for your application, with custom cut-to-fit capability down to 1-foot lengths.
